Description

Technical Field

[0001] The present invention relates to the field of homogenization, and in particular to a high-efficiency fluorite powder homogenization device. Background Art

[0002] In the fluorspar powder-sulfuric acid method, the acid powder ratio is a crucial step in ensuring a complete reaction, and the uniform metering and stable delivery of fluorspar powder are key to maintaining a stable acid powder ratio. Due to the large number of fluorspar powder suppliers, varying origins, and production methods, as well as batch drying and layered stacking, the quality of fluorspar powder varies.

However, during the stirring process, some fluorite powder will accumulate at the bottom of the device, causing the stirring mechanism to be unable to effectively contact this part of the fluorite powder, thereby affecting the homogenization of the fluorite powder.

[0013] The beneficial effects of the present invention are: 1. The present invention provides a stirring mechanism. When homogenizing the fluorite powder, the fluorite powder is placed inside the tank. After the filling is completed, the tank cover is closed. At this time, the stirring mechanism is started to stir and homogenize the fluorite powder. During this period, the motor is started, and the motor drives the screw to rotate. When the screw rotates, it drives the moving block to move back and forth. When the moving block moves, it drives the scraper to move synchronously. At this time, the scraper scrapes the fluorite powder deposited on the bottom of the tank so that the fluorite powder can be flipped upward. During this period, the rotating shaft drives the gear As the moving block moves, the gear will mesh with the rack when it moves, and the gear will drive the rotating shaft to rotate under the meshing action of the rack. The rotating shaft will drive the stirring blade to rotate at the same time. At this time, the stirring blade will stir the fluorite powder that is flipped upward. The cooperation of the scraper and the stirring blade can effectively stir the fluorite powder, so as to improve the homogenization effect of the fluorite powder and prevent part of the fluorite powder from being deposited at the bottom of the tank, which will cause the stirring mechanism to be unable to effectively stir the deposited fluorite powder, thereby affecting the homogenization of the fluorite powder. 2. The present invention provides a stirring mechanism, an impact mechanism and a dust reduction mechanism. When the fluorite powder is stirred by the stirring mechanism, the turntable will drive the pin to rotate synchronously with the rotation of the screw. At this time, the pulling rod will push the piston plate to slide back and forth up and down inside the pulling cylinder under the action of the pin and the sleeve. At this time, the gas inside the pulling cylinder will be compressed, and the compressed gas will be transported to the inside of the conduit and ejected downward through the jet pipe. At this time, the ejected gas can be used to reduce dust on the raised fluorite powder. Since the turntable is made of cam material, when the raised end of the turntable contacts the push plate during rotation, the push plate will drive one end of the swing plate to deflect downward under the action of the turntable, and the other end of the swing plate will deflect upward. At this time, when the swing plate deflects upward, it will drive the impact block to impact the bottom of the tank body, thereby processing the fluorite powder adhering to the inner wall of the tank body through the vibration generated during the impact, so as to improve the homogenization effect of the fluorite powder.
